从童养媳到丁克家庭：生物相对论与人类社会

From child wife to DINK family: the principle of biorelativity and human society

人类是高级生物,但适用于人类社会的生物理论却很少。生物相对论是指生命的两个基本性状即繁殖力和寿命间的反向关系。本文试用这一关系分析人类社会从多子多孙的传统观念到少生、不生的丁克家庭和独身主义的社会风俗时尚转变的生物学基础和必然性。撰写过程中,还意外地发现了"北方人为什么比南方人高"这一有趣问题的解释。

The principle of biorelativity posits a negative relationship between fecundity and lifespan, the two basic genetic traits.
